Hi,

Just want to bring it to you guys' attention that Alpha Vange is distributing market data illegally and legal actions have been taken against the company. I suggest you guys to switch to another provider immediately to avoid service disruption.

Original proof of illegal activity can be found here: https://www.reddit.com/r/algotrading/comments/hnxoy6/beware_alphavantage_is_not_a_licensed_provider/

The following market data has disappeared due to legal actions and more will be coming soon:

• US real-time data (now they only have end of day data)
• LSE
• NSE
• ASX
• Torronto stock exchange (TSX)
• All Nordic exchanges
• All Baltic exchanges
• Moscow stock exchange
• Istanbul stock exchange

I'm just as disappointed as all of you that a great idea was so poorly executed and based on entirely illegal foundation to begin with.

When using this library stocks with symbol containing & failing

When querying the same stock twice in a row using the same client the resulting time series returns different data:

require 'alphavantagerb'
client = Alphavantage::Client.new key: "YOURAPIKEY"
stock1 = client.stock symbol: "LYPG.FRK"
puts stock1.timeseries.close.first
stock2 = client.stock symbol: "LYPG.FRK"
puts stock2.timeseries.close.first

Returns

2019-02-08
231.2000
2019-02-08
231.1000

Obviously both values should be the same. Using the Timeseries.new method to retrieve both seems to be fine.

Hi guys,

Just wondering if we can create a new Gem wrapper for Finnhub stock API as well : https://finnhub.io/ . You can access 60 free calls/minute with intraday data going back for many years with Websocket for free. I think this is a way better alternative for alpha vantage. 5 calls/minute is a bit of a headache with alpha vantage.

You have very strict (exact major & minor version) dependencies:

  s.add_dependency "httparty", "0.15.6"
  s.add_dependency "humanize", "1.7.0"

It could lead to conflicts if ruby project use this gem with other gems depending on httparty and humanize.

I believe, it would be very useful to make dependencies more loose:

  s.add_dependency "httparty", ">= 0.15.6"
  s.add_dependency "humanize", ">= 1.7.0"
